JOHN LEE, OF \VELLSVILLE, OHIO.

LARD-L'AMP.

Specification of Letters Patent No. 2,854, dated November 21, 1842.

To all whom iimay concern Be t known that 1, JOHN LEE, of ellsvllle, 1n the county of Columbiana, in the State of Ohio, have invented a new and use- )urning lowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1, is an exterior view of the lamp; Fig. 2, a vertical section; Fig. 3, the piston and tube separate.

The construction of my lamp is as follows: In a saucer formed similar to that of the common. hand lamp a reservoir E is fastened of sufficient capacity .to contain the lard, this may be made cylindrical or square to suit the fancy of the constructor, onto this reservoir a cover B, is fitted, from the rim of which studs (6,) project; these enter a bayonet formed slot (0,) which when the cover is put on and turned to one side hold the cover down, from the center of this cover a tube A rises up the top of which may be enlarged if desired, and into the top is screwed the cup holding the wick tubes in the usual way this tube A, is made to turn in a collar in the cover B, and from its lower end the thread of a screw projects inward at 0, within this tube another ofsmaller diameter F works up and down, having a spiral groove around its outside, into which the thread 0, fits. On the lower end of the tube F apiston D is fitted of the size and form to fit the reservoir having a hole in its center of the size of the tube F and being packed around its edge so as to work tight ing around by being forced into the solid lard which holds it firmly it will thus be seen that as the outer tube is turned the inner one will be forced up or down, and when the reservoir is filled with lard or other substance, as the piston is forced down, the lard will be made to rise up the cente tube to supply the wicks.

WVhat I claim as my invention and desire to secure by Letters Patent is- The combination of the inner tube F, and piston D, with the outer tube A, constructed and arranged in the manner and for the-purpose herein set forth.

JOHN LEE.
